In the duo of Diemo Schwarz and Hans Leeuw, both players will challenge each other on the extremities of sound through improvisation. Hans’ manipulated Electrumpet sounds are recorded in Diemo’s digital instrument CataRT where specific bits of sound are recombined and transformed, challenging Hans to come up with more extreme sounds surpassing his own originals. Thus we get a game-like improvisation battle between two players who control and master their respective instruments.
The unpredictability of the sound produced during the improvisation is always part of the challenge. Not to know what can happen is an integral part of the performance.
